Project Meeting 2022.03.16

Notes

This was an ad hoc additional meeting to discuss the vehicle type model.

The vehicle type data file

• There is a miles-per-gallon (MPG) variable in the vehicle type data file.
• How do we use this information downstream?
  • The MPG is made available to the model for choosing vehicles types (this component), but auto operating cost per mile is more than just fuel efficiency.
  • The cost per mile (different from MPG) needs to be written into the vehicle type model.
  • Those costs per mile will be made available to downstream models where a vehicle has been allocated.

How do we handle vehicle “year”?

As implemented:

• User gives a scenario year
• Vehicle data file has the fleet mix by year, ages are calculated by difference from scenario year.
• RSG will change the name of this setting from "scenario year" to something more descriptive and specific, like “fleet year”.

What should we call “option 2” and “option 4”?

• The group discussed whether they need to be separate model components.
• We will retain the existing structure where the two model systems are activated from the same component by making different settings.
• The actual names for these options will be decided later.

Future tasks not a part of Phase 6B

• Creating profiles of future fleet, either as a one-off forecast or an automatic parameterized tool.
• Sensitivity testing of the vehicle types model.
